Abstract

Horizontal curved bridge is a bridge with a cross section of a curved steel I-girder that requires complex geometry and has certain requirements. which different between a straight bridge with a horizontal curved bridge that is in addition to the vertical bending effect and the shear effect is also influenced by torsional effects, lack of stability, and special constructive attention, and consideration of system behavior in the analysis. The purpose of writing this final project is to be able to do the bridge structure modeling using Midas Civil software, to design the structure of the horizontally curved steel I-girder bridge, and Obtaining the dimensions of I-Girder steel horizontally curved bridge that is able to resistance the effects of curvature and loads that work in accordance with predetermined conditions, and know the behavior of elements from horizontally curved steel I-Girder bridge. This design refers to AASHTO LRFD 2012 and design carried out namely three continuous span (42 m + 55 m + 42 m) by using two pieres. the dimensions of steel I-girder with 2000 mm girder height of 20 mm body thickness, top flange width 500 mm thickness 25 mm, and bottom flange width 600 mm thickness 40 mm. From the results of the girder design there are some of conditions which can be said to be extreme because comparison between the compressive stress with capacity almost the same, that is 99.8% at the inertia-x on maximum positive moment fatigue condition, 95% at the inertia-y on maximum positive moment strength lime state condition, and 98% the maximum positive moment Constructibility on torsion. This proves that every agreed has extreme. However, this value is still within safe limits in accordance with the standards used.

Abstract

Introduction: Tuberculosis is a chronic infectious disease caused by the bacteria mycobacterium tuberculosis. TB cases in Indonesia are in second place with the largest number of TB sufferers in the world after India and West Sumatra is one of the provinces in Indonesia with the number of cases in 2020 as many as 14,398 cases based on the report of the Indonesian Ministry of Health. Tuberculosis (TB) has various risk factors. There are several factors that influence the incidence of TB, including environmental factors, external environment, socio-economic and behavior. Therefore, the purpose of this study is to determine the risk factors for the incidence of tuberculosis in Padang City. Methods: This study is an analytical observational study using a case control design by presenting data descriptively and spatially. The focus of this study is the analysis of spatial autocorrelation of tuberculosis incidence in Padang City from January to December 2024. Data collection was carried out by observation, interviews, and measuring air quality in selected sample houses. Results And Discussion: The results of the analysis found a positive autocorrelation between sanitation facilities factors and tuberculosis incidence (clustered pattern) and no autocorrelation between knowledge, behavior and environmental conditions factors and tuberculosis incidence. There are 5 sub-districts that are spatially significant between knowledge, behavior, sanitation facilities and environmental conditions, namely Padang Barat, Padang Timur, Kuranji, Bungus Teluk Kabung, and Lubuk Kilangan Sub-districts. Conclusion: Based on the results above, it can be concluded that there is autocorrelation between sanitation facilities and tuberculosis incidence and there is no autocorrelation between knowledge, behavior and environmental conditions. Therefore, it is expected that the community can implement a clean and healthy lifestyle and related agencies can re-inspect people's homes and educate people infected with tuberculosis.
